Has anyone bench tested a logic module? Basically I want to power it up outside of a car and connect to it via the usb module I have soldered on to it. I understand that the power module sends it like 8v or something odd like that, has anyone tried it with a 9v battery, or even 12v ac adapter? Or maybe someone with more EE experience than I can tell me how to knock a 12v ac adapter down to 8v. If I can get it working I may try and hook my stimulator for megasquirt up and see if I can get the tach signal to cooperate.
